422 Deep-sea Trawling off the S.W. Coast of Ireland : 



Bulla semilcBvis^ Seguenza. 

 From 1000 fath. 



Cylichna (Sao) ovata, Jeffreys. 



From 1000 fath. 



This species was obtained in various parts of the North 

 and West Atlantic in from 350 to 1000 fath. bj the ' Porcu- 

 pine ' and ' Challenger ' expeditions. 



SCAPHOPODA. 



Dentalium candidum, Jeffreys. 



From 1000 fathoms. 



One of the two specimens obtained is very fine, and con- 

 siderably exceeds the dimensions quoted by Jeffreys. It is 

 85 millimetres in length ( = 3| inches), and 8 in diameter at 

 the aperture. The longitudinal stride in this exam[)le can be 

 traced from the a])ex along about half the length ; and at a 

 little more than an inch from the broader extremity a strongly 

 marked reparation of an injury is visible, the result of an 

 accident or the attack of an enemy. 



This species was first obtained by the ^ Valorous ' expe- 

 dition in from 410 to 1750 fath. ; it was subsequently dredged 

 at several stations off the west and south of Ireland by the 

 ' Porcupine ' expedition at depths ranging from 420 to 

 2435 fath. 



Cadulus OUvij Scacchi. 



From 1000 fath. 



Two specimens from the above depth agree exactly with 

 others in the ]\Iuseum obtained by the ' Porcupine ' expe- 

 dition, which Jeffreys * associated (and probably correctly) 

 with this species. The latter were dredged off the west 

 of Ireland in 1230 fath., and south of Ireland in 539 fath. 



Pelecypoda. 

 Montacuta substnata, Montagu. 



From 50-60 fath. 



As usual around the British coasts, these specimens were 

 dredged attached to the spines of Spatangus 2>u7-j)ureus.
